SAP HANA Architecture Explained: Components, Benefits, and Tradeoffs

SAP HANA is an in-memory, multi-model database architecture that integrates transactional and analytical processing on a single platform using columnar storage and a centralized index server. This design enables high-speed performance and scalability through efficient data compression, parallel processing, and a robust persistence layer. However, these benefits require careful management of memory requirements, query optimization, and overall architectural complexity.
